  1. It's been too long BinRev! Who wants to see what I've been up to?

  2. I did a little research into tuners. I'm thinking something like MythTV as a backend with 2 InfiniTV 6 tuners in the same box and then just have a strong data link over the air gap between my house and the "guest" house. After that I'll just use some Raspberry Pi's as the frontend boxes with some USB IR remotes. Linux apparently has builtin support via evdev for IR remotes now. So that's pretty righteous. That should be the simplest way to do it as far as I'm concerned. The trick will be getting a fat enough wireless pipe between the two houses to support 3 or 4 HDTV streams. I'm guessing a pair of decent 802.11ac routers will suffice.
  3. How am I supposed to offer my neighbor half priced cable TV like that? No, sadly that won't work. I'm considering something like an HD HomeRun and then something like AirMAX to connect the guest house to the main house. I wish there were something a little more seamless though.
  4. I suggested a script to update DNS, but that would take a few hours to propagate whereas DynDNS would be a lot faster. I just don't like the idea of having to configure a load balancer for that. We could pretty much fail everything over automatically as we are, but our external users would still be unable to reach us for a few hours until the new DNS records propagated.
  5. So for the past week I've been doing some light reading on cable TV and Internet, because I was bored. I learned a little bit about DOCSIS 3 and whatnot, and I got to thinking about some things, and I figure this is probably the best place to ask about this. Let's say I had two houses relatively near one another, maybe one's a guest house... so it's on the same property... which already has cable service... and before you ask, I just don't feel like installing a splitter and running a coax cable all the way to the other house, okay? I wasn't expecting the Spanish Inquisition! But anyway, yeah, no legal issues with this. So let's say I wanted to transmit digital TV from one house to the other, OTA style. I found some different transmitters online that I think would do what I want, but there's a catch. I want to encrypt the signal between the houses. So I need some logic somewhere along the way that takes the TV signal, converts it to encrypted data, transmits to the other location which then returns the data to its original format and hooray a wireless television bridge. Any ideas from the cavalry? The real kicker is encrypting the traffic being sent OTA for less than 4 figures! EDIT: I should also note that I'd like to use a directional antenna, because I only want to broadcast to this one specific location. Looking at equipment online, if I cut out the encryption, I could use a UHF transmitter to do what I want, but where's the fun in that? I'd rather use something like Ubiquiti's AirMAX and send/receive encrypted TV. EDIT 2: Looking at TV tuner cards, I'm assuming it would be super simple to take the signal from a coax cable and turn it into network data. The complicated part appears to be encrypting that data and then returning that signal to coax elsewhere. THE FINAL EDIT: I'm looking into software defined radio for this as well now! RTL-SDR = $30 TV receiver, right? This is going to be a fun project!
  6. I would like my traffic to automagically failover in the event of an outage, but from what the network engineer at my place of work says, that would require dynamic DNS, which always seemed a bit sketchy to me.
  7. Hey! I wanna make a supercomputer but I'm currently, "balling on a budget". I want it to be rackmounted! Why, you may be asking? Cuz how cool would that look in my basement!? I have no idea what I'd use it for yet. Probably mining ethereum until that goes proof of stake, then some folding, some hash cracking, and a little bit of deep learning. So let's say my budget is $1000. Here's what I want.... GPUs I've messaged every nearby craigslist poster with an AMD card better than a 7850. I want as much parallel processing power as possible. I'm looking to use Virtual OpenCL (VCL) to cluster my machines. Think I can get 6 really nice cards for under $400? Ideally someone has a mess of 7950's they're not using anymore. Hardware Rack mountable server chassis and a server rack. I know I can get 2 4u server chassis' and a shitty tripp lite rack for something like $220. I like the idea of 2 computing nodes and a third master node. CPU/MOBO I need to get as many GPUs per motherboard as possible. A typical rack server chassis only has 7 expansion slots and each video card is conceivably going to be 2 slots wide. This means a max of 3 video cards per board and one single width slot leftover. Based on PCIe lane width I'm going to want to go with the AMD 990FX/SB950 chipset combo to save money but not sacrifice too much performance on the PCIe lanes. I'd probably pick up a 6 or 8 core FX processor. Intel is out of the question with my budget. Looking at mobos that meet this criteria, the Asus M5A99FX Pro R2.0 seems like a good option for ~$85 used on eBay. It also has a 4th PCIe slot, which could be useful because of my next point.... Networking Eventually I'll need a darn good network connection. For now GB ethernet is fine but maybe, just maybe, i'll switch to Infiniband later. If I do that, I'm going to need a free PCIe slot for the networking card. This will also had some significant cost to the project. Power Now this is where things get expensive. A decent ATX 1500W PSU is like $250 used, and I need 2 of those! Any ideas? Storage In order for this supercomputer to be truly super, I'm going to need fast storage...what should I do? An SSD would be the obvious choice, but how am I going to afford 2 of those on my budget? What about RAM, do I need a lot of RAM on a system like this? Any ideas BinRev?
  8. You guys are the best. To answer your questions I was looking for hardware for about 30 satellite sites that require a secure VPN connection back to corporate HQ and good QoS over that connection. The sites are practically SOHO, so I didn't need fiber or anything like that. Just so you know, I stuck with Ubiquiti for the switches. At the moment they just need 8 port managed switches at each site, but as you said Tekio, it's always good to plan for growth, so I bumped that to 16 port PoE switches and with the money saved by not purchasing overly priced Meraki devices and licenses, I recommended rackmountable APC UPS systems, a set of nice WAPs, and Ubiquiti cloud keys (hybrid cloud device that lets you manage a site remotely and has no licensing cost) Glitch, for the edge devices I remembered working with pfSense a while ago, and I asked myself, "What would systems_glitch do in this situation?" So I recommended they buy 33 pfSense security appliances.
  9. I'm looking for network hardware for a midsized business. My only stipulations are that it has to be highly configurable for VPN access (I'll need both site to site connections and a site to user connection) You guys typically give the best insight for this type of thing, so I figured I'd ask around here. So far I've looked at Meraki equipment and Ubiquiti. Both look like they'll be able to do what I want, although the Meraki has the added benefit of being extremely easy to configure and has web management for when I'm not in the office (which is 99% of the time). On the plus side for Ubiquiti, it's cheaper and does everything just as well as the Meraki without any regular license costs. Thoughts? Opinions? Words of wisdom? Other suggestions?
  10. I know I'm late to this topic, but one thing I've been doing with my Windows 10 boxes is, regardless of if they're a virtual machine or not, I run VMWare's OS Optimization Tool against them, and selectively disable things with it. For instance, none of my Windows 10 enterprise machines should be able to connect to WiFi except the laptops, everything else gets hardwired. So, I disable WLAN AutoConfig and all the other WLAN and WWAN features/services with the tool so as to prevent Joe user from bringing in his USB WiFi stick because his wired connection isn't working that day, connecting to an insecure public WiFi network, and then trying to do his work. The tool can also disable the fax services and the telnet ones. It's not intended as a hardening tool, but a solid choice nonetheless, and if there are Windows features you don't use, it can disable them for you. I never use Windows Backup as I have a backup solution, so that's disabled on my machine. Overall, on the actual VMs anyway, the machines I optimized with the tool use about 400MB less RAM on startup than a not optimized machine.
  11. Seeing The Strokes in two days!

  12. Brutal! Now that's some hacking! Did you use firebug for that? Also, I loved pfsense last I got to play with it. I worked in a lab that did a lot of network security work, but had really low funds, and they wanted to purchase an enterprise grade firewall for their business connection. When it became clear that wasn't exactly possible, my suggestion was pfsense running through a spare parts server (we had a lot of parts for building good desktop computers) and a 2 port 10gbps PCIe 2.0 ethernet card. (~$400) I never got to realize that dream before leaving, but I can only imagine what a kickass edge device that would have been!
  13. I had a similar issue programming something for a coworker that emulated keystrokes in order to automate a task that otherwise would take hours of pointing and clicking. My only advice is to make sure you followed everything in the docs to the letter, and when in doubt, add a little delay between keystrokes. If nothing else, you slow the program down enough so that you can better debug things. For instance, I was using a shortcut key, but it wasn't behaving the way I thought. I added a delay, and was able to discern that my active window wasn't being set properly, and so my emulator wasn't working within the correct program. Good luck!
  14. Port 25 is a great place to find "good SMTPs". I highly recommend checking it out. The Yelp reviews are great. Otherwise I know of a nearby mega church still running a highly misconfigured server circa 2002.
  15. Bought my first house! Moving in tonight!
